Toal l whom it may concern:

Be it known that I, JosnF LATZEL, asubject of the Emperor ofAustria-Hungary, and resident of 0/0 Disconto Gesellschaft,

53'Cornhill, London, E. (1, England, have invented certain new anduseful Improvements in Driving Axles Particularly for Motor-Vehicles, ofwhich the following is a specification.

This invention relates to driving axles of the live type, with thedifferential gear arranged between one s ring and the adjacent roadwheel, articu arly for use on motor vehicles, and as for its object toprovide a substantial construction, in which the rotating parts do notcarry the load, and in which the portion of the axle which carries theload is continuous, asis also the rotating 'portion. I

According to this invention, the load and road wheels are carried by atubular member, in which is contained the rotating member. At one end ofthis latter, one road wheel is attached, while the other end isconnected by a sleeve to one member of the differential gear. The othermember of the differential gear is connected by a sleeve lying outsidethat just mentioned, to the other road wheel'.-

In this way a form of continuous axle is obtained, which is naturallystronger than the construction in which the axle is divided,

and carries the load, as is commonly the case.

The accompanying drawings show diagrammatically how this invention maybe carried into effect.

Figure 1 is a longitudinal section of one form of axle constructed inaccordance with this invention, while Fig. 2 is a part sectional viewshowing a modified form of a'xle.

In the construction illustrated in Fig. l, the tubular part A carriesthe load, for which purpose 'the vehicle springs B areattached to thistube. "Arranged within thetube A is an undivided rotating shaft To theleft hand end of the rotating shaft C is attached one road wheel hub D.The method by which this is attached to the shaft forms manyotherconstructional details are shown merely diagrammatically. In this casethe connection is shown as a square C on the shaft, engaging a similarholein the hub. To the other end of the 'rotatingshaft C is fixed asleeve E the other end of Whicli carries one of'the'd'itferential gearmembers F.

The other gear member G is connected to the right hand wheel hub H whichlies outside the sleeve E, and these members F and gaged by thedifferential pinions J and K journaled in casing L as usual. On thiscasing L is mounted the driven gear member, which may be a chainsprocket M. Obviously, suitable bearings and bushes arearranged wherenecessary.

In operation, it will be seen that the drive transmitted to the drivenchain sprocket M and easing L passes by way of the differential pinionsJ and K to the gear members F and G, as usual. The first of thesetransmits power, by means of the sleeve E, to the right hand end of thetubular axle, and thence to the rotating shaft G, and thus to the hub Dand left hand road wheel, while the other gearmember drives direct on tothe hub H,

and right hand road wheel.

It will be seen that the load is supported on the tubular member A,which is undivided and continuous throughout the width of. the vehicle.

' The construction shown in Fig. 2 is similar to that shown in Fig. 1withthe exception that the gear members F and G now drive on to theopposite'road wheels from which they drove in the previous construction.In this case the chain sprocket M is connected to the differential gearcasing L by means of a web? L 1 The pinions J and K mesh with the gearmembers F and G as before, but in this case the gear wheel G isconnected with the sleeve E which is fixed 'to the rotating shaft C, atthe other end of which the left hand wheel connected to a plate F towhichis attached a drum 0, the webOPof which is attached to the righthand wheel hub H. 'The operation is the same as in the previousconstruction, and the results obtained are similar in that the tubularmember carries the load, and it, and .the rotating memberC, arecontinuous throughout' the width of the vehicle. Ob-

viously, in place of a chain sprocket, any other driving member may beemployed, and this, and the driving pinion, may be contained Within asuitable casing.

I/Vhat I'claim as my invention, and desire to secure by. Letters Patentof the United States, is

1. In combination, a driven gear member, an undivided stationarysupporting axle member road Wheels supported thereon and Gare enhub isfixed. The other gear member F is a-continuous undivided rotating axlemember connected to the driven ear member and. to the road Wheelssubstantially as set forth.

y 2. In combination, adriven gear member,

5 an undivided stationary supporting axle member, road wheels supportedthereon, a differential gear supported thereon and connected to thedriven gear member and a continuous undivided rotating axle member con-10 'nected to the difierential gear and to the road wheels,substantially as set forth.

3. In combination, an undivided tubular stationary sup orting axlemember, a" contlnuous undlvl ed rotating axle member con- 15tamed-therein, a differential gear supported thereon, one road wheelsupported on said tubular axle member and connected tothe rotatlng axlemember, a sleeve mounted on the tubular axle member and connected to therotatingfaxle member and to the difier- '29 ential-gear, one-road Wheelmounted on said sleeve and connected to said difierential gear andadrivengear member connected to said differential gear, substantially asset forth.

In testimony whereof I have signed my 25 name to this specification inthe presence of two subscribing witnesses.
